Should David convince the Engineer race that the xenomorph race deserves to be human?

Why should everything go down within the human scale. As if us humans are not enough anthropocentric. So the question is now: should we introduce "alienphobia" into the Alien franchise? And what is next?: "cosmophobia"?, so it turns out all we are seeing is just a holographic projection? Alien should be about aliens. Dan O'Bannon must be rolling in his grave right now.

David is hostile because he isn't human, which makes the logic of the question. David was made in man's image, therefore it's the human image that David connects to empathy.

For this reason, it makes sense for David to think of the issue in human terms; of course, it doesn't have to be that way, and David could reach out to the Engineers without using the concept of humanity, but just the concept of sentience and self-awareness

To rephrase the question: should David try to get the Engineers to help xenomorphs become more self-aware?

I thought that David would be the one to convince the Engineers that the xenomorph race deserves to kill humans, for humans are inferior in his eyes. He might even have the xenos wipe out the Engineers as well since they created the inferior species.

He can try, it would be fun.

The Engineer in Prometheus didn't seem to react well when David spoke to him, so I hope the Engineers in the next film are like that. They'll probably even be a little angrier after they see what David has done and I think they'd find it particularly insulting that a being/thing like David utilized some of their technology and attempted to create/manipulate life and now thinks of himself as a god. At least that's how I hope it'll turn out. Who knows how Ridley has thought of this and how he intends to tie all this together.

I'd even suggest that David becomes the Space Jockey, but it's a staged reality; it's possible that the Space Jockey was never a sincere accident, as is implied, but was a ritual performed by David as a way to coax the Engineer race into helping the Xenomorph race.

Is it possible, that the Space Jockey is David, and David became the Space Jockey deliberately as part of a deal with the Engineers to help the xenomorphs?

We still don't know who the Master of the Engineers is and what their creation to the Black Goo or it's origin is or why the Engineers mutate, nor how many planets they have seeded over the million years, or how many species they have created. It could be thousands. For all we know, the mural in Prometheus in the ceiling, depicted their ruler.... David is not after the underlings but their creator.

 Saturnyne  I think the mural idea is good. It would be a great irony if the xenomorphs are actually based on a species that supersedes the Engineers; so the rulers of the Engineers, as you put it, look identical to the xenomorphs. Perhaps that could be a third act twist of the film, where David's xenomorphs interact with the xenomorph beings that are the top of the hierarchy

I wonder why the resemblance between the shoulder - arm - hand of the bird like creature in the submissive posture from the Prometheus mural. Could it be some coincidence only?

daliens I see your point. There are similarities. I just hope that the next film shows David offer to sacrifice himself to the Engineer race - or to the actual top of the hierarchy - so that the xenomorphs he created can become like the top of the hierarchy. The film could show David's xenomorphs being taught or changed by xenomorph-looking beings into becoming like them. 

David becomes the Space Jockey, which is a ritual that David has to experience as part of the deal, and in return his xenomorphs get to evolve; it would be a great plot twist to the mythology, as people have always assumed that the Space Jockey was an accident, and an actual tragedy. Not only this, but if David is the Space Jockey as part of a ritual it would close the gap between Alien Awakening and the beginning of Prometheus.

The start of Prometheus showed an Engineer performing a ritual, so that life could exist; it makes sense for David to bookend the story, and emulate that Engineer
